Is alcohol tolerance an early pregnancy symptom?

Hi all!

First off I want to say that I obviously do not encourage drinking while pregnant!!

But I’m about 7dpo and I drank 2 nights ago and I usually can drink a good amount and never puke. I’ve only puked once while drinking before in the past. I drank about 3 beers and some wine and spent all night puking and was nauseous all day the next day. My tolerance is pretty good. So I was just wondering if any of you all have had that happen before finding out that you’re pregnant?
